Abstract (en)
[origin: WO2022195050A1] The invention relates to a method and to a correspondingly designed system for predicting the operation of a technical installation in which a process-engineering process having at least one process step runs, wherein datasets characterizing the operation of the installation and containing values of process variables are acquired in a time-dependent manner and stored in a data memory and, in a learning phase, a self-organizing map (SOM) is learned using historical datasets per process step or batch, symptom threshold values and their tolerances are ascertained and stored for each neuron per SOM and all permissible temporal profiles of victor neurons are ascertained and stored per process step or batch for all timestamps. The invention is characterized in that, in an evaluation phase, a time starting from which the operation of the technical installation should be predicted is determined, in that at least one victor neuron profile for the overall process step or batch is then ascertained using current datasets of at least one process step by way of the learned victor neuron profiles, and in that the values, stored in the neurons of this victor neuron profile, of the process variables are displayed on an output unit after the previously determined time in the form of a predicted profile. By predicting the future dynamic process behaviour, the invention allows early corrective interventions in the operation of a technical installation.
